Information About 6SE7023-2EA87-2DA0
The 6SE7023-2EA87-2DA0 braking unit is part of the Siemens SIMOVERT MASTERDRIVES series, a trusted family of high-performance industrial drive components. This unit regulates DC link voltage during deceleration by diverting excess energy through braking resistors, thereby maintaining system stability and preventing overvoltage faults. With a continuous power rating of 20 kW and a current capacity of 38.8/16 A, it is ideal for medium to high-power drive applications. The IP20 protection rating makes it suitable for cabinet installation, while its modular design ensures seamless integration into existing SIMOVERT drive configurations. Although discontinued since October 2011, the unit remains a critical spare for maintaining legacy systems, with newer Siemens SINAMICS braking units available as migration alternatives.
Key Features:
- High-Power Braking Capability: Handles up to 20 kW of regenerative energy for stable drive operation.
- Wide DC Voltage Range: Operates efficiently between 510–620 VDC.
- Dynamic Energy Dissipation: Controls braking torque and prevents DC link overvoltage.
- Industrial Reliability: Engineered for use in demanding industrial automation environments.
- Compact Modular Design: Integrates seamlessly with SIMOVERT MASTERDRIVES systems.
- IP20 Enclosure: Provides safe operation within protected cabinet environments.
- Thermal Protection: Ensures consistent performance under heavy braking conditions.
- Legacy Compatibility: Suitable as a spare or replacement for discontinued SIMOVERT drive systems.
The 6SE7023-2EA87-2DA0 delivers the reliability and control required for efficient braking in regenerative industrial drive applications.
